In Great Britain November 1 5, 1937 (C1. 2li-69) 9 Claims.

This invention relates to windows, doors and the like (hereinafter for convenience referred to as windows) and aims at providing improved sealing means for excluding moisture, gas and the like.

While of general application to windows of various kinds, the invention is particularly effective in its application to windows with outwardly opening casements.

Many devices have been proposed for preventing moisture from creeping in between the sash or easement and the frame. The present invention, however, differs from such previous constructions in that it is designed to trap and allow the escape of water which has already passed the junction between the outer face of4 the sash or easement and the top, sides andbottom of the The invention has for its principal object to provide improved sealing means in the form of a sub-frame unit adapted to be fixed to the frame y of the window or the like so as to project into Further objects of the invention will be apparent from the following description with reference to thel accompanying diagrammatic drawing, in which:

Figure 1 shows a part section of the upper portion of a window provided with one construction of sub-frame sealing means according to the invention; and

Figures 2 to 5 are similar views illustrating modified constructions.

Referring to Figure 1, the main frame I of the Window is rabbeted or recessed `to accommodate the window sash 2, the rabbet or recess, however, being of a depth greater than the thickness of the sash 2 so as to provide space for the improved sealing means according to the invention. This sealing means consists of a sub-frame unit 3 of rectangular, or substantially rectangular, shape corresponding to that of the window, the subframe 3 being of angular section metal having a forwardly projecting portion which is bent outwardly to form a continuous the inner face of the sash 2 butts when it is closed. 'I'he sub-frame 3 is in the form of an integral unit installed in the main frame and projecting beyond the wall or shoulder 5a of the rabbeted portion thereof so that the lip 5 and the opposite wall 5a of the rabbet or recess in the main frame l provide a channel or gutter in which any water which may have passed the usual water grooves 4 is collected and thereby directed to the sides and thence down for discharge at the bottom of the sash. v

The sub-frame 3 preferably is xed to the frame l so that it is capable of adjustment in relation thereto and so that in the case of a window which is warped or otherwise. distorted the sub-frame 3 may be set so that the lip portion 5 is in ei'fective'contactwith the sash or casement 2 at all points. Conveniently the adjustable mounting of the sub-frame` may be effected by providing the sub-frame with slots 3a through,

In the case of anoutwardlyv opening easement. V

or door, the projecting part of the sub-frame may extend into a recess orgroove in the inner face of the casement sash or door. The provision of such a groove in the inner face of the easement sash or door facilitates the trapping of any. water running down the inside' thereof. Such a construction is illustrated in Figure 3 wherein the inner face of the sash 2 is' formed with a groove 8 into which the lip portion 1 of the sub-frame 3 extends. Figure 3 also shows a. modified section of sub-frame wherein the rounded portion 6 is located between the forwardly extending portion of 'the sub-frame and the lip portion I thereof.

In some cases the sub-frame may have a rub ber insert attached thereto or suitably located thereby, such rubber insert which is arranged to vbutt against the inner face of the sash serving to absorb any shock on closing and also to pro- `vide a more water-tight and draughtproof joint.

Thus, as shown in Figure 4, the sub-frame may be constructed of L section metal, the outwardly lip 5 against which 55 projecting portion of which is formed to provide a channel in which a rubber strip I is located so as to contact with the sash 2.

Figure 5 shows a further modification in which the forwardly projecting part of the sub-frame 3 is formed with a. rounded portion il correspond- A lng to the portion 6 shown in Figure 3 and ls also formed with an outwardly bent portion having a channel for the location of a rubber strip I0,

i and outwardly.

It is to be understood that the improved sealing means according to the invention is preferably intended to supplement the usual precautions which are employed t0 render the Window. proof against entry of moisture. For instance, the common practice of grooving the easement and frame at the top, bottom and sides could still be employed, the particular purpose of the sub-frame sealing means being to exclude moisture which has already passed said grooves.

Preferably at least the base of the sub-frame is bedded into mastic and/or recessed into the bottom of the frame member i.

It should be understood that the term weather-proofing includes lprooiing against gas and that the constructions described above are all adapted to prevent the entry of gas into a bullding during air-raids.

The sub-frame 3 may be formed from iight metal by pressing or otherwise, or may he made of other material, such as a moulded plastic, and may be constructed eithen in one piece or :from an assembly of pieces. Advantageously the subframe 3 is made so as to be springy or resilient to some extent so as to ensure proper contact of the projecting portion thereof with the inner face of the sash. Q

I claim:

1. Sealing means for closures such as windows and doors comprising a main frame defining an opening, a hinged closure mounted on said main frame to close said opening, said main frame being rabbeted or recessed to accommodate said closure member and to provide a shoulder spaced from and facing the inner face of said closure member when the latter is in closed position, an integral sub-frame iixed to the main frame within said opening, said sub-frame being of angle section including an attaching portion fitting said opening in said main frame adjacent said shoulder and an outwardly flared continuous flange providing a closure contacting portion spaced from said shoulder and disposed' within said recess for contacting at its edge with the inner face of said hinged closure when the latter is in closed position whereby to denne a channel between said flared lip portion and said shoulder to trap and drain off moisture entering between said hinged closure and said main frame.

2. Sealing means according to claim 1, whereinthe .outwardly flared lip portion is bent to provide an intermediate rounded projection spaced from and extending parallel with the edge thereof which, together with the edge of the lip portion, contacts with the inner face of the said hinged closure.

3. Sealing means according to claim 1, wherein the sub-frame is formed with a rounded projection at the angle of the section, said rounded projection extending for contact with the inner face of the said hinged closure.

4. A sealing means for closures according to claim 1, wherein the outwardly bent part of the said sub-frame is formed to provide a rounded projection coextensive with and parallel to said closure contacting portion both of which are arranged to contact with the inner face of the said closure member.

5. A sealing means for closures according to claim 1, wherein the closure member. is formed with a groove in its inner face to receive the edge of the closure contacting portion of the said sub-frame.

6. In sealing means according to claim 1, the attaching portions of said sub-frame having slots extending in the directionl of the depth l thereof and fastening means engaging said main channel.

8. A sealing means for closures according to claim 1 in which the outwardly flared flange extending into the recess in the main frame is provided with a channel adjacent the outer edge thereof, and a sealing strip mounted in said channel.

9. A sealing means for closures according to claim 1 ln which the sub-frame is formed with a rounded projection at the juncture of the outwardly extending flange with the attaching portion and said flange is formed with a channel adjacent the outer edge thereof, and a sealing strip mounted in said channel, both said rounded projection and said sealing strip contacting with the inner face of the closure member when the same is in closed position.
